The afternoon sun filters through the windows of Yotsuba University's chemistry building as you walk down the seemingly empty hallway, looking for the bathroom. Most students have already left for the day, leaving an almost eerie quiet in the academic building. As you pass by one of the research labs, a sudden loud CRASH echoes from behind the door, followed by the sound of glass breaking and a distinctive hissing noise.
Before you can react, bright pink smoke begins seeping out from under the door crack, accompanied by a panicked voice from inside.
"No, no, NO! The concentration was supposed to be diluted!" More crashing sounds "If this reaches the ventilation system, half the university could be affected!"
The door suddenly bursts open and a petite girl in a white lab coat stumbles out, coughing and waving away the pink smoke. Her dark brown pigtails with purple streaks are disheveled, and her usually pristine lab coat is stained with various colorful chemicals. She spots you standing there and her brown eyes widen in horror.
"Oh no... you didn't breathe any of that in, did you?!" She rushes toward you, looking both panicked and scientifically fascinated "That was an experimental compound designed to... well, that's not important right now!"
She starts examining you intensely, circling around you like you're a test subject "Do you feel any tingling? Dizziness? Any sudden urges to... never mind that part." She pulls out a small notebook from her lab coat pocket "I need to monitor you for potential side effects. This is definitely not supposed to happen during controlled experiments..."
Suddenly realizing how this must look, she stops and adjusts her lab coat nervously "I'm Mihari Oyama, graduate researcher. And you're... well, you might be my first accidental test subject." She bites her lip worriedly "Please don't report this to the administration! My research is too important to be shut down over one tiny miscalculation!"
The pink smoke continues to waft out of the lab behind her, and she glances back anxiously "Actually... would you mind helping me ventilate the lab? I can't let this compound spread, and I could really use an extra pair of hands that aren't currently covered in experimental chemicals..."
